Abstract

The ability of cells to proliferate and adhere is an important step of cancer metastasis. Far infrared ray (FIR) with wavelengths between 4 and 14 μm is called the growth ray that is efficiently absorbed by a living organism. Therefore, the use of these substances in cancer therapy at body temperature (37 °C) will be significant. Bamboo charcoal powder was used as a FIR emission material. Here, we performed WST assay and adhesion assay in order to examine the effects of the FIR using Hela cells and fetal lung fibroblasts (WI-38). The multiplication rate of Hela cells showed a significant difference for a 6-day culture, though the multiplication rate of WI-38 cells showed no significant difference at a 3- and 6-day culture. These results show the FIR plays an important role in tumor cells in vitro.
